Compositional, Unconventional & Advanced Processes Simulator

GEM

GEM™ is the leading reservoir simulation software for compositional, chemical, and unconventional Equation of State (EoS) based reservoir modelling.

Accurately replicates the subsurface fluid flow and interactions to assist in field optimization and to maximize hydrocarbon recovery. GEM is widely used to capture unconventional shale liquids production and is the gold-standard simulator for CO2 and H2 storage processes.

Unconventional Oil & Gas

Simulation for Unconventional Reservoirs

Simulate natural and hydraulic fractures, multi-component adsorption and desorption, geomechanical effects, inter-phase mass transfer, multi-phase diffusion and non-Darcy flow for unconventional shale as well as coal bed methane production.

Enhanced Oil Recovery (EOR)

Improve and Optimize Recovery Factors

Understand the impacts of key phenomena including miscible/immiscible displacement, chemical EOR, and non-steam based thermal recovery processes when improving and optimizing the recovery factor of an oil and gas asset.

Modelling data for simulation
Chemical EOR (cEOR)

Advanced Evaluation and Design

Design and evaluate the effectiveness of chemical additives with advanced cEOR features such as polymer, surfactant, foam, and ASP type enhancements.

Low Salinity Waterflood

Optimize Recovery and Reduce Environmental Impact

Maximize oil recovery and reduce environmental impact with accurate simulation of Low Salinity Waterflood (LSW) mechanisms, including geochemistry and wettability alterations, accounting for ion exchange, and zeta potential influences on the process.

Carbon Capture & Storage (CCS)

CO2 Injection for Subsurface Viability Assessment

Simulate the long-term effects of carbon dioxide (CO2) injection into the subsurface environment, in particular saline aquifer or depleted hydrocarbon reservoirs, thereby helping determine the viability and reducing the risk of any CCS project
